or maybe lose some of this...

 

hahahaha

 

The CF driveshaft will cost around $1,100-1,300, the aluminum ones are a less expensive alternative. You won't be able to lose much weight without making major sacrifices.

 

im about to trade stock seats + 400$ for these sparco seats with rails ?? thinks its a good deal ??

 

Those are good. You should get those.

 

does any1 know which series they are ?? want to find out the weight

 

Racing seats! The OEM seats weigh a TON!

 

do you track your car?

 

Best weight reduction---In most cases we can stand to lose a few pounds from our gut "spare tire". Also, don't drive around on a full tank. I usually put 7 gallons per fill.

 

Unless you going to track your car, buying Infiniti just to gut it out seems a bit pointless. Just my opinion though. Z would have definitely be a better choice.

 

That makes too much sense. Party pooper.

 

yah, captain obvious stikes again lol

 

The OP never said anything about gutting the car

 

The front fenders weigh 25lbs? Hard to imagine, considering they're made of sheet metal. I've held a 350z fender in my hands (close enough to the G fender for government work). I wouldn't say that it weighs more than 8-9 pounds. For the price of the CF fenders, the weight loss is negligable.

CF driveshaft isn't worth it unless you're planning on putting down some serious horsepower. The G comes with an aluminum shaft, and the weight reduction is negligable. Maybe 3-4 pounds. Granted, yes, this multiplies considerably when it comes to spinning inertia, but unless you're racing the car, this doesn't seem worth the cost.

If you wanted to do any kind of CF replacements, doors and trunk would be the best bets.

Lightweight seats are a good bet, as well. But the easiest way to shed weight in the G is to strip a lot of the sound deadening out.

OP, honestly, if you want a car that's good for weight reduction, but retains the 2+2 attributes, you'd be better off getting a early-90's 300zx...

 

Ah the 300ZX, that was my car before the G. I love the G, but I still wish I would have kept the Z. I did not have the 2 + 2 model. A lot of people told me I made a mistake getting rid of the Z (I tend to agree sometimes) but I look at the G and those feeling go away (a little...).
